Thanks again for your responses :)

I did this, and was able to get the Regex example to work. However,
when I went to test the Thread library (another that I am interested
using), I run into another linking problem but not during compile
time. I'm able to compile and link correctly:

make -k all
Building file: ../main.cpp
Invoking: GCC C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d"
-MT"main.d" -o"main.o" "../main.cpp"
Finished building: ../main.cpp

Building target: boost_thread_test
Invoking: GCC C++ Linker
g++ -L/home/bgarrison/local/lib ./main.o -lboost_thread -o
Finished building target: boost_thread_test

Build complete for project boost_thread_test

but when I try to debug (using the debugger in Eclipse), I get the
following message:

/home/bgarrison/Code/boost_thread_test/Debug/boost_thread_test: error
while loading shared libraries: cannot open
shared object file: No such file or directory

This is strange to me because, I know the file it's looking for is in
the directory specified by the -L parameter. :(

Thanks for any and all advice.
